Stirrerheads<br />
‘O’ and oil film sealed stirrerhead<br />
• For use up to 350 °C<br />
• For vacuum and pressures up to 25 Bar<br />
• See pages 57–61 for description<br />
Lowest cost option for undemanding applications. It<br />
requires constant attention and, at higher pressures,<br />
frequent maintenance. The ‘O’ ring imposes a high<br />
and variable counter-torque on the shaft.<br />
Hence it is unsuitable for use with the torque measurement<br />
unit.<br />
Mechanically sealed stirrerhead<br />
• For use up to 350 °C<br />
• For vacuum and pressures up to 50 Bar at<br />
4 000 rpm.<br />
• See pages 62–67 for description<br />
This triple ball bearing stirrerhead is practically<br />
maintenance free. Years of use without maintenance<br />
are normal. Pressure has no effect on the shaft<br />
counter-torque. The counter-torque varies from<br />
0.2 Nm at 100 rpm to 0.9 Nm at 4 000 rpm.<br />
Magnetically coupled stirrerhead<br />
• For use up to 350 °C<br />
• For vacuum and pressures up to 50 Bar (special<br />
versions available for up to 150 Bar 1 600 rpm)<br />
• See pages 68–75 for description<br />
This stirrerhead has a static seal. No gasket comes<br />
into contact with moving parts. Pressure has no effect<br />
on the shaft counter-torque. The counter-torque<br />
varies from 0.2 Nm at 100 rpm to 1.5 Nm at 1 500 rpm.<br />
